in Tomago, New South Wales in Australia, has been operating since 1983 and today is Australia’s largest aluminium smelter, producing up to 590,000 tonnes of aluminium per year.

The company contributes $2.2 billion annually to the Australian economy, of which $800 million is spent locally. The smelter produces 590,000 tonnes of aluminium every year, which is 37% of Australia’s primary aluminium. 90% of the product made at Tomago is exported to the Asia-Pacific region.

Innovation at Tomago

Tomago’s emissions are among the lowest recorded by any aluminium smelter in the world. Emissions created during the smelting process pass through ducting to treatment plants, known as dry scrubbers, where impurities are removed.

Tomago has a comprehensive environmental management program, focusing on emissions control and incorporating one of the world’s most advanced pollution-control and environmental protection systems.

Among the emissions carried to the dry scrubbers are fluorides, which, with other fumes and dust, form particles that are captured in large filter bags. These particles are returned to the smelter as feed material. This process is more than 99% effective in removing fluoride from the gases collected.

Tomago community

At Tomago, we have an out-of-pay donation scheme by which employee donations are matched dollar-for-dollar by the company. In 2023, our Workplace Giving Program raised $130,000 with $80,000 donated to the Westpac Rescue Helicopter Service and the rest being split between The Starlight Foundation, Jenny's Place, Calvery Mater Haematology Unity and Hunter Melanoma Foundation.

Sourcing locally

Tomago contributes $2.2 billion annually to the Australian economy, of which $800 million is spent locally.

Tomago has partnerships with more than 500 suppliers from the Hunter Region, and works with them to deliver results through continuous improvement and innovation.

Tomago employs 1000+ staff (full time equivalent) as well as 200 contractors. Our staff are drawn from a significant geographic area throughout the Hunter Valley and Central Coast, travelling from as far as 100 kilometres south, 80 kilometres north and 50 kilometres west of the plant. Ensuring that our people are safe while they are at work is one of the main drivers of our business.

Repowering the smelter

Tomago uses 950MW of constant power, which is 12% of New South Wales’s demand – the largest load in Australia. We’re aiming for more than 50% renewable electricity by 2030, and aspire to 100% renewables by 2035.
